Portage, MI (CNN) - Meet Sydney, she's a Beagle Terrier mix, and a new mother of 5 kittens?

Last week Heather Rector brought the kittens home after they were rescued from a construction site. She says it didn't take long for Sydney's maternal instincts to kick in.

"Two days of them being here, she was fully lactating, and ever since her breasts have been completely full, and she hasn't stopped lactating yet," said Heather.

Now Sydney is feeding, bathing the kittens and she won't let them wander far without bringing them back to her bed. What's ironic is that a vet said this type of relationship was impossible.

Jhapel Santiago is Sydney's owner, he says she's already had 3 litters of her own, but she seems happier now that she has little ones to look after again.

"She has always been a nice dog, so to see her doing that, it's a shocker at first, but that's just typical Sydney," says Jhapel. 

As a new mother herself, Rector says she's proud of Sydney's compassion.  "You don't see a lot of people or animals do that anymore, and i think she did the exact thing i would have done."
